PRESSURE-RELEASING MECHANISM.

.. Specification of Letters Patent. Patntga Feb. 27, 1917.

Application filed November 16, 1916. Serial No. 131,734.

.To all whom it may concern:

Be it known that I, PAUL H. SCHENDLER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Pressure-ReleasingMechanisms; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, forming part of this specification.

My invention relates to means for releasing the rolls of wringers inemergency cases, and has for its object to provide a simple, safe andconvenient apparatus, whereby such release may be effected instantly,and without danger to the wringer or its material parts.

The features of my invention will appear, hereinafter, and areillustrated in the accompanying drawings, in which Figurel, is a sideview in elevation, of a portion of a clothes wringer having my invention.embodied therein.

Fig. 2, is an endwise view of the same.

Fig. 3, is a top Or plan View thereof. 1

In these drawings A and A indicate the bifurcated end posts of thewringer frame;

, B and B indicate the upper and lower wringer rolls; C indicates thepressure springs in the end frames A and A; D and d-d indicate the guidemember'connecting .the topof the roller springs C C, all of .which partsare of usual and ordinary construction.

Between the upper ends of the bifurcated end posts A and A, I place across bar E, having therein screws EE, which engage the arms d (l, ofthe spring guide D, for the purpose of adjusting the pressure of thespring C upon the upper roll B.

Secured'against the end surface of the bifurcated side post A, is aplate F, which 'holds the upper ends of the bifurcated end post A fromspreading apart. Secured in the plate F, by means of a pivot f, is ahook F, which extends over the upper sur--' face of the end of the bar Eadjacent there- -to, and prevents that end of the bar E from beingforced upwardly by springs 0 The hook F, is provided with ears f,

the action of the which overlap the plate F; and said hook is alsoprovided with a spring 7, for the purpose of maintaining said hook in anupward position, as shown by. full lines in the drawings. The cars f,which overlap the plate F, as shown in Fig. 2, prevent the hook F frombeing moved forwardly between the upper ends of the bifurcated' endposts A, when the transverse .bar E, is in the position shown by brokenlines in Fig. 1, so that when the said bar E is forced downwardly in theposition thereof shown by full lines in Fig. 1, the hook F, will not'beso far thereunder-that it will prevent the bar E, from being forced backinto its normal position, but that said hook F will be thrown outwardly,as shown by broken lines in Fig. 1, by the bar E being forced downwardinto its normal position, when the spring 7 will force the hook F. toagain overlap the upper side of the bar E adjacent to said hook. a

The opposite end of the bar E is secured in the position thereofindicated by full lines in Fig. 1', between the upper ends of thebifurcated end post A, by means of a G, which, like the plate F, on thebiplate furcated end post A, at the, opposite end of the wringer, spansthe upper end of the bifurcated end post A, thereby preventing the armsthereof fromspreading. This plate G, is provided with ears G in which isplaced a. transverse pivot H, which engages the end of the transversebar E, adj acent thereto, and maintains the same in its normal position,as shown in the drawings.

Secured upon the bar E, is a slidable plate J, which is provided with aslot J, through which the'adjusting screw E passes; the plate J, beingsecured upon the 'bar E by means of a screw j passing through a slot j.'For operating the slide'J, I provide a lever K, which is supported uponthe bar E by means of a bifurcated bracket K secured upon the bar 13 bymeans of a screw or bolt K The lever K, is provided with a notch, 71:,with which an upturned end j on the sliding plate J intermeshes. I alsoprovide a spring L between the lever K and the bar E forreturning thelever K to its normal K; a'doWnward stroke being. the easiest and mostnatural movement of a person Whose fingers might be accidentally caughtbetween the rolls B B. This movement of the lever K, as shown by brokenlines in Fig. l, forces the slide J to push the hook I into the positionthereof shown by broken lines in Fig. 1, which releases the bar E andpermits the springs C C to force the bar E upwardly as shown by brokenlines in Fig. 1, thus releasing all pressure upon the roller B.

Having thus shown and described my in vention so as to enable others toconstruct and utilize the same, what I claim as new and desire to secureby Letters Patent is:

1. The combination in a device of the class described, of a transversebar adapted to be placed between the upper bifurcated ends of the endposts of aclothes wringer, pressure regulating screws in said bar, aplate secured upon the upper end of one of the end posts of the Wringer,a spring pressed hook pivoted in said plate adapted to engage the upperside of the end. of said bar adjacent to said hook, ears on said hookoverlapping and engaging said plate, a sliding plate secured on saidtransverse bar, one end of which engages said hook, and a verticallymovable spring pressed lever mounted on said transverse bar engagingsaid slidable plate, substantially as set forth.

2. The combination in a device of the class described, of a transversebar adapted to be placed between the upper bifurcated ends of theend'posts of a clothes wringer, a plate secured on one of said wringerend posts havingears thereon, a pivot pin passing through said ears andone end of said transverse bar, a spring pressed hook secured on theother of said wringer end posts adapted to engage the upper side of theopposite end of said transverse bar, a lever and slide mechanism adaptedto disengage said hook from said bar, substantially as described.

In testimony whereof I affix my signature.

PAUL H. SCHENDLER
